An improved parameterization of tidal mixing for ocean models

Creator:: Schmittner, A. and Egbert, G. D.
Abstract:: Two modifications to an existing scheme of tidal mixing are implemented in the coarse resolution ocean component of a global climate model. First, the vertical distribution of energy flux out of the barotropic tide is determined using high resolution bathymetry. This shifts the levels of mixing higher up in the...

Robust principal component analysis of electromagnetic arrays with missing data

Creator:: Smirnov, M. Yu and Egbert, G. D.
Abstract:: We describe a new algorithm for robust principal component analysis (PCA) of electromagnetic (EM) array data, extending previously developed multivariate methods to include arrays with large data gaps, and only partial overlap between site occupations. Our approach is based on a criss-cross regression scheme in which polarization parameters and spatial...

Ionospheric current source modeling and global geomagnetic induction using ground geomagnetic observatory data

Creator:: Sun, J., Kelbert, A., and Egbert, G. D.
Abstract:: Long-period global-scale electromagnetic induction studies of deep Earth conductivity are based almost exclusively on magnetovariational methods and require accurate models of external source spatial structure. We describe approaches to inverting for both the external sources and three-dimensional (3-D) conductivity variations and apply these methods to long-period (T≥1.2 days) geomagnetic observatory...

Satellite-based detection and monitoring of phytoplankton blooms along the Oregon coast

Creator:: McKibben, S. M., Strutton, P. G., Foley, D. G., Peterson, T. D., and White, A. E.
Abstract:: We have applied a normalized difference algorithm to 8 day composite chlorophyll-a (CHL) and fluorescence line height (FLH) imagery obtained from the Moderate Resolution Imaging Spectroradiometer aboard the Aqua spacecraft in order to detect and monitor phytoplankton blooms in the Oregon coastal region. The resulting bloom products, termed CHL[subscript rel]...

Comparing the spectral lag of short and long gamma-ray bursts and its relation with the luminosity

Creator:: Bernardini, M. G., Ghirlanda, G., Campana, S., Covino, S., Salvaterra, R., Atteia, J.-L., Burlon, D., Calderone, G., D'Avanzo, P., D'Elia, V., Ghisellini, G., Heussaff, V., Lazzati, D., Melandri, A., Nava, L., Vergani, S. D., and Tagliaferri, G.
Abstract:: We investigated the rest frame spectral lags of two complete samples of bright long (50) and short (6) gamma-ray bursts (GRB) detected by Swift. We analysed the Swift/BAT data through a discrete cross-correlation function (CCF) fitted with an asymmetric Gaussian function to estimate the lag and the associated uncertainty. We...

Seasonal phenology and abundance of Leucopis argenticollis, Leucopis piniperda (Diptera: Chamaemyiidae), Laricobius nigrinus (Coleoptera: Deridontidae) and Adelges tsugae (Hemiptera: Adelgidae) in the Pacific Northwest USA

Creator:: Kohler, G. R., Wallin, K. F., and Ross, D. W.
Abstract:: Adelges tsugae infested western hemlock trees were sampled periodically for 1 year at two locations in Oregon and Washington to compare the phenology and abundance of three associated predators (Leucopis argenticollis, Leucopis piniperda, and Laricobius nigrinus) and their host. On each sample date, two 3–10 cm long terminal twigs were...

On sea-ice dynamical regimes in the Arctic Ocean

Creator:: Lukovich, J. V., Hutchings, J. K., and Barber, D. G.
Abstract:: Central to an understanding of evolution in sea-ice characteristics in response to climate change is an understanding of sea-ice dynamics. In this study, we investigate regional differences in ice dynamics in the Beaufort Sea and High Arctic using high-frequency ice buoy (beacon) data deployed during the SEDNA and IPY-CFL field...

Assessment of thermal embrittlement in duplex stainless steels 2003 and 2205 for nuclear power applications

Creator:: Tucker, J. D., Miller, M. K., and Young, G. A.
Abstract:: Duplex stainless steels are desirable for use in power generation systems because of their attractive combination of strength, corrosion resistance and cost. However, thermal embrittlement at intermediate homologous temperatures of ~475 °C and below, limits upper service temperatures for many applications. New lean grade duplex alloys have improved thermal stability...
